Claims. (01. 171119) My invention relates to means for connecting lead wires toan inductance and more particularly to a connection which is slidably mounted on the lead wires to form a support therefor.

5 Among the objects of my invention are: To

provide a means for making a variable connection to an inductance; to provide a clip connector for an inductance coil slidable on a lead wire for varying said inductance; to provide a slidable clip connector for an inductance which serves as a support for the lead wire to the inductance; and to provide means for reducing losses in lead wires to an inductance carrying high frequency currents.

Other objects of my invention will be apparent or will be specifically pointed out in the description forming a part of this 'specifica-.

tion, but I do not limit myself to'the embodiment of my invention herein described, as varioils forms may be adopted within the scope of the claims.

In the drawing, which illustrates apreferred terminal for system lead wires 6 and '7, or as terminals for an inter-inductance link 8, I will describe only one of the slidable clips 9, as they are all alike.

The terminal ends of the lead wires, or interinductance links, are extended parallel to the longitudinal axis of the inductance, adjacent the periphery of the coil. It is customary in high frequency circuits to make these lead wires of copper tubing.

The clip 9 is drilled to form a hole 10, fitting the lead wire, and the clip is then split to form a slot 11. A set screw 12 is threaded through the slot above the hole to iorm clam ing means by which the cliprnay be solidly secured to the lead wire.

Each clip is provided with two contact springleaves 13 riveted to the body of the clip, and formed with an out-turned bend at their ends in order that they may be easily inserted on and As my invention may be used either as a firmly grip a single turn of the copper ribbon.

In operation, the set screw is loosened, the clip slid along the end of the lead wire to the desired location, the spring leaves are pushed onto the ribbon, and the set screw tightened.

In the case of system lead wires such as wire 6, the clip thus forms the sole end support of the lead wire.

In the case of the inter-inductance link 8 the clips form the sole support of the entire link.

I am thus able to firmly support the ends of my lead wires without losses due to contact with insulators, and at the same time am able to vary the point of inductance connection by sliding the support clip along the end of the lead wires. In many installations involving the high frequency circuits of'radio transmitters, I have been'able to support all lead wires from their ends, without resort tointermediate insulating supports, and as a consequence, high frequency losses are reduced to a minimum.

I claim:

1. Means for making a variable connection to an inductance, comprising a lead wire to said inductance, a clip adapted to grip a single turn of said inductor, said clip being slidably mounted on said lead wire and forming the sole end support for said lead wire.

2. Means for making a variable connection to an inductance, comprising a lead wire to said inductance, a clip adapted to grip a single turn of said inductor, said lead wire forming a sliding foundation for said clip, said clip forming the sole end support for said lead wire.

3. Means for making a variable connection to an inductance, comprising a lead wire extending parallel to the central axis of said inductance and adjacent the circumference of said inductance, a clip slidably mounted on said lead wire, and means on said clip for gripping a single turn of said inductance, said clip forming the sole end support for said lead wire.

4. Means for terminating a lead wire on an inductance comprising a clip slidably mounted on the end of the said lead wire, said clip forming the sole end support for said lead wire, and means on said clip for gripping a single turn of said inductance.

5. Means for variably interconnecting inductances comprisinga wire link approaching both of said inductances, a clip slidably mounted on each end of said link, means for gripping a single turn of inductance on'each of said clips, said clips forming the sole, support for said link.
